It has been found desirable to provide an improved catch and latchconstruction for extension bracelets having overlying bracelet portions,one portion being provided with an adjustable catch which may beselectively positioned along the length thereof, and the other portionhaving a latch at its end which may be releasably secured to the catch.The essential features of the invention reside in a novel constructionfor facilitating the adjustment, securing andrelease of the catch andlatch parts.

Referring to the drawings, the bracelet I0 includes a lower section ll,see Figs. 2 and 3, which has an end hook I! at one end for attachment toone bail of a wrist watch, and a slide loop l3 at the other end throughwhich an upper bracelet section I4 extends, the further end of thesection l4 having an end hook [5 for attach- .2 is afcntral verticalsection there- Application 'octobe'r 23, 194 SerialNo; 415,234? tolaims.(a m-.239)

base |8,1.pr'eferably of stamped metahhavirig a bottom" plate l9 and twoside plates 2!], each side "plate having an opening 21 for receiving apivot and catch pin 22. The bottom plate has a shallow central, recess23, Which may have cross ribs 24,

to better lock "with 'the'lower surface 'of the bracelet section H incooperation with an upper lock part 25, which has" a halt, lower portion26 terminating inian j upstanding edge 2,1, and having twoside plates"28v which each have slightly inclined slots 29 in which the ends of thein 22 are" receiving, the upper edges of'the sideplates beingconcealedbeneath inturned edges 3llof the side plates 20.

As shown inFig. 5, the proportions of the p arts permit thebraceletsection. H'fto be. received. between the bottom plate {lficof the baseI8 and the flat lower portion 28 of the upperlockpart, the slots 29permitting slight relative movement of the parts to accommodate thelower bracelet section, which may have projecting ribs 3| on the uppersurface thereof. A clamp element 32 is also mounted on the pin 22, thiselement being made of sheet metal and shaped to provide a central recess33, spaced end clamp teeth 34, and

a finger tab 35. When the finger tab is lifted to release the clampteeth, the upper lock part is released, andthe catch may be moved alongthe lower bracelet section to adjust the total bracelet length, thesecuring of the catch in place placing the free central portion of thepin 22 in position to receive the cooperating latch parts. I

Referring to Figs. 9 to 14, the latch l1 includes a box-like housing 36which has a forward positioning plate 31 and spring pressed retractablelatch teeth 38. The latch assembly is accomplished by providing a frame39, see Fig. '11, having a base plate 40, side plates :4l, and a forwardextension '42 which is'bent at right angles to provide the plate 31. Thebase plate is slight- 1y depressed at the rear, as indicated at 43, to

provide a rear portion 44 having end lock tabs 45, the end of thebracelet being positioned on the rear portion 44 and secured thereto,preferably by spot welding; a cross slot 46 is provided at the forwardend of the frame.

A finger piece 41, see Fig. 12, has a button 48,

a pre ss plate 49 atlright angles thereto, stop lugs 50,'and afingernail lip 49:: to be used for sliding the finger piece 41 beingpassed through the slot to position the press plate 49 in parallelrelation to the positioning plate 31. A tooth support'5l, see Fig. 14,is of generally rectangular shape, with two spaced latch teeth 52 and iarearrecess' '53 adapted to receive a spring element 54. v The supportand spring 54 beingplaced on the base plate 40 with the I press plate 49between the teeth 52; as hereinafterdescribed, and, the spring pressingagainst the bracelet end, a cover element 55 is mounted" to close theframe 39, thecover element having"- a front plate 56, slots 51' for:free movement of.

the teeth 52, the front p1ate55 having end lugs 58 adapted to seat incorresponding recesses 59 in the side walls M of the frame, see Fig. 11,

the rear of the cover element being depressed I as indicated at EO, andbeing aligned with'the rear portion 44 of the frame to vbe secured bymeans of the lock tabs j45 which are bent over Y to seatin the depressedp rtion. i Referring nowto-Fig. 14, the teeth-'52 as'illustratedto]provide lal outments 6| which are are cut contacted by the lugs'5U ofthe finger piece Al; the teeth have roundedsurfaces 62 which permitsnapping of the teeth over the. pin 22 of V: the catch, see Fig. 10, andundercut surliaces 63 which prevent accidental release of the pin after1 snapping in.

The above described "chnstruction thus utilizes a simple arrangement ofeasily manufactured and assembled parts, preferably made of stampedsheet metal the latchteeth are, readilysnapped over .the'free portion ofthe catch'pin. after the ,ipositioning plate is extended over thepin 22,and securely held until the finger piece button 48 is pushed back, thus,forcing' the teeth support and the teeth back against the "spring 54 topermit lifting release "of the latch from the catch.

7 Although I have described a specific'constructional embodiment of myinvention, it isobyious that changes in the size, shape proportion, andrelative arrangement of the parts, may be made to meet therequirementsior different bacelet designs, without departing from thespirit and the scope of the invention as defined in the appended claims.
